WhatIsSolderMask?
ASolderMaskisaprotectivepolymercoatingappliedtoprintedcircuit boards(PCBs)to:
Preventsolderbridging
Protectcoppertracesfromoxidation
Improveelectricalinsulation
Enhancemechanicaldurability
Whilepermanentsoldermasks(likeLPImasks)remainontheboard,
PeelableSolderMaskisatemporaryprotectivelayerspecificallydesigned toberemovedafterthesolderingprocess.
WhatIsPeelableSolderMask?

WhyPrecisionMatters
Inhigh-volumePCBmanufacturing,a singlesolderbridgeorunwanteddeposit cancompromiseperformance,reliability, andcompliance.Wavesolderingexposes boardsto245°Cto260°Cmoltensolder temperatures.
Industrydatasuggeststhatimproper maskingcontributestoupto15–20%of soldering-relatedPCBdefectsinwave solderinglines.Usinghigh-quality PeelableSolderMasksignificantly reducesthisrisk.
